Résumé
Short umbilical cord syndrome, also known as the limb-body wall malformation complex and the body stalk anomaly, is a poorly defined sporadic group of congenital anomaly charaterized by a complex set of disruptive abnormalities having in common the failured closure of the ventral body wall. This disorder is charaterized by a short or absent umbilical cord and disruption of the lateral body wall, spine, limbs, face, and cranium, isolated or in combination. Recently, we present a case of short umbilical cord syndrome which found in a term baby, so we report a case of short umbilical cord syndrome with brief review of literature.

OBJECTIVE: Quantitative analysis of both apoptosis and proliferation should provide important insight into tumor biology. The aim of this study is to clarify the significance of apoptosis in the progression of uterine cervical neoplasia, including cervical intraepithelial neoplasia, and microinvasive and invasive squamous cell carcinoma categories. in relation to cell proliferation. METHODS:: Forty five cases of cervical intraepithelial neopasia. 10 of microinvasive carcinoma, and 10 of invasive squamous cell carcinoma were examined using formalin fixed and paraffin embedded samples. The TdT mediated dUTP-biotin nick end labelling(TUNEL) method for apoptotic cells, and Ki-67 and Topo-II immunojhistochemistry for proliferating activity were performed. RESULTS: Apoptotic and proliferative indices, calculated by counting positive nuclei among 1,000 nuclei of cancer cells, should significant positive correlation with histological malignancy grading in CIN and tumor cell invasion into stroma, and showed also significant positive correlation between them. CONCLUSION: These findings suggest that apoptosis in cervical neoplasia may be closely related to tumor cell differentiation and progression.

OBJECTIVE: We analyzed 200 cases of prenatal amniocentesis and compared them with other reported studies. Thus we propose the necessity of metanalysis for prenatal amniocentesis. METHOD: We analyzed 200 cases that have undergone amniocentesis at Masan Samsung hospital from January 1996 to December 1997. The results of our study was compared with other reported studies of amniocentesis by indication and maternal age. The proportion of age-class and indication are compared between previous study subjects and our 200 cases. RESULTS: Triple marker abnormality was the most common indication of amniocentesis(51%) and the most common age distribution was 25-29 years (43.5%). Chromosomal aberration was diagnosed in 20 cases (10%) of which the numerical aberration was 9 cases (4.5%) and the structural aberration was 11 cases (5.5%). 5 cases (2.5%) out of ll cases of the structural aberration were normal variant. There were 7 cases (trisomy 21) of autosomal aberration and 2 cases (Turner syndrome) of sex chromosome aberration. Arnong the structural aberration, there was only one reported case of 46, t(7:10) reciprocal translocation. There were no cases of fetal death except for a little self limited preterm labor. There were no neonatal complications. In the comparison of indication and maternal age with other studies, abnormal triple test was the most common indication of amniocentesis. The number of young pregnant women under 35 years old who underwent genetic amniocentesis was increased year by year. CONCLUSION: Triple maker screening test and genetic amniocentesis become popular method of antenatal diagnosis in Korea. Now, it is the proper time to establish standard indication of prenatal amniocentesis in this country by systemic and objective statistic examination. So we address the need for metanalysis in our country as comparing with other studies.

Our purpose was to study the correlation between elevated maternal serum alpha-fetoprotein(MSAFP) or human chorionic gonadotropin(HCG) levels and pregnancy-induced hypertension (PIH), preeclampsia, preterm delivery. MSAFP and HCG levels were measured in stored second-trimester(14~22 weeks) serum obtained from 510 women. The criteria for patients with unexplained MSAFP elevations were a MSAFP level 2.5 or greater multiples of the median(MoM) and HCG elevations were a HCG level 2.0 or greater multiples of the median(MoM) excluding multiple pregnancy, fetal malformation or death on ultra-sonography and molar pregnancy. In contrast, patients with MSAFP levels 0.5 to < 2.5 MoM, HCG levels < 2.0 MoM were served as controls. Women with elevated HCG levels had more significant association with PIH than control group(22.2 % versus 3.4 % ; p < .005). Elevated MSAFP was significantly associated with preeclampsia(7.7 % versus 1.1 % ; p < .05). But no significant differences were observed in the incidence of preterm delivery. We suggested elevated second-trimester MSAFP or HCG levels appear to be correlated with high risk for PIH and preeclampsia. So, These patients require careful monitoring with adequate obstetric managements.
